HandyDraw does not implement smoothing properly

[GoogleCodeExporter]

Smoothing in HandyDraw only seems to smooth the interior of shapes, not the 
stroke outline. Due probably to the PGraphics2D rendering object used by the 
class.

Need to examine what happens when a PGraphics object is created through 
PApplet's createGraphics() method to ensure we are using the correct renderer 
with correct settings.
